MAC Lavender Whip is one of those cult shades that I never understood, as you can see from my old photo

I own a tube (somewhere) and as you can tell from my lack of enthusiasm I never reach for it.
It really all boils down to preference and what you suit and my little round face does not carry purple tones
all that well but for those that adore the shade and have waited forever for it's return your wait is nearly over.
Come April in the US and May in the UK MAC's Baking Beauties collection will hit the counters 
and you can grab a Lavender Whip lipstick and many other sugary sweet shades to boot!
